-
-    Implements all methods and operations of
-    ``MutableMapping`` as well as dict's ``copy``. Also
-    provides ``lower_items``.
-
-    All keys are expected to be strings. The structure remembers the
-    case of the last key to be set, and ``iter(instance)``,
-    ``keys()``, ``items()``, ``iterkeys()``, and ``iteritems()``
-    will contain case-sensitive keys. However, querying and contains
-    testing is case insensitive::
-
-        cid = CaseInsensitiveDict()

-        cid['aCCEPT'] == 'application/json'  # True
-        list(cid) == ['Accept']  # True
-
-    For example, ``headers['content-encoding']`` will return the
-    value of a ``'Content-Encoding'`` response header, regardless
-    of how the header name was originally stored.
-
-    If the constructor, ``.update``, or equality comparison
-    operations are given keys that have equal ``.lower()``s, the
-    behavior is undefined.
